Product Overview
Neoprene Sealing Washers place a compressible ring between mating surfaces around a hole or connection. When oil and water are both present, the selection should account for each exposure separately, including any cleaning solution introduced during maintenance. A broad fluid category does not describe every additive or operating condition the rubber may encounter.
The washer can be customized in size, material, hardness and color. Match the bore and outside diameter to the supported area of the joint, then consider the thickness available after assembly. The rubber should contact the intended faces without being pinched by an edge or displaced into the opening.
During sample evaluation, use the actual fluids and relevant contact duration. Inspect the washer for swelling, softening or a changed seating shape after exposure. If a joint leaks, examine the mating faces and assembly method as well as the compound; replacing the washer with a harder version will not necessarily correct a damaged seat. Keep the selected material consistent when replacing parts in an established assembly.
- Material options

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
